Please help me add and vote for any books that fit this description:

"Best science fiction that focuses on the soft sciences (psychology, sociology, anthropology, or political science etc.), or just science fiction books with a big focus on the culture or functioning of alien, far future, or otherwise speculative societies."

I couldn't find any similar list on goodreads yet.

Gateway has elements of psychology throughout the novel

Feel free to add it and any other books you can think of to the list.
